Just some points for thought.....
You are aware that Paul called it his Gospel, are you not?
2Ti 2:8 Remember Jesus Christ, risen from the dead, of the seed of David, according to my gospel:
He also included himself with others, as you mentioned.
Gal 1:8-9 But though we, or an angel from heaven, should preach unto you any gospel other than that which we preached unto you, let him be anathema. As we have said before, so say I now again, If any man preaches unto you any gospel other than that which ye received, let him be anathema.
I would say that Paul's message was oriented toward the Gentiles and certain ways of Jewish thinking had to be removed. His Gospel was the same, as Peters are any of the Apostles but Paul did have to correct the Jewish Apostles on several points:
1). The need for circumcision - was cast out by joint agreement but Paul was the one arguing for it's removal.
2). Peter was rebuked by Paul because he was guilty of Hypocrisy, giving into separation of the Jews from the Gentiles.
3). Sent one of the Gospel writers away, (believed to be John Mark) because he couldn't get along with him.
Additionally, I would say read John's Gospel and notice how many times he speaks of Election. So to in Paul's writings:
2Ti 2:10 Therefore I endure all things for the elect's sake, that they also may obtain the salvation which is in Christ Jesus with eternal glory.
Just some things that crossed my mind when I read your post.

John's gospel, as I have explained earlier in this thread here https://christianchat.com/threads/why-have-the-sign-gifts-ended.196068/post-4429813 , there are plenty of verses from him that linked born again to "obeying the commandments".
One thing for sure, you will not find salvation by faith alone in the finished work of Christ on the cross, apart from works in any of his writings.
